Specification of Letters Patent.

Patented Dec. 29, 1908.

To all whom it may concern.:

Be it known that I, HERBERT W. WOLFF, a citizen of the' United States, Iresiding at St.

Louis, in the State of Missouri, have inventl i ed a certain new and useful Car-Truck, of the axles 27 carrying the wheels 28,.v Thexoil s l I l l movable compression member 25 adapted to hold the bolster 15 in position and to receive an end thrust from the webs 23. 4 26 are the oil boxes in which are journaled which the following is such a full, clear, and 1 boxes 26 are held in position by means exact description as will enable any one skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part otthis specilication.

My invention relates to car trucks for railway cars, and more particularly to-the manner of forming the side frame of the truck.

The object of my invention is to provide a side frame whi lh will be as simplelas possible of construction and at the 'same time f will have the greatest possible amount of 'strength with the least possible use of metal.

In the accompanying drawings, which illustrate a car truck made in accordance with my invention, Figure 1 is a top plan view on a reduced scale, Fig. 2 is a section on the line 2-2'of Fig. 1, Fig. 3 is an enlarged view of the'main casting of the side frame, Figs. 4

and 5 are detailed views, showing the brakehanger and Fig. 6 is a side elevation.

Like marks of reference refer to similar parts in the several views'of the drawings,

10 is the bottom member of the side frame. This member is T-shaped in cross section, as best shown in Fig. 2,'and is preferably provided with strengthening webs 11 and 12. The upper face of this member 10 forms a flat spring seat 13 for supporting the lower ends of the springs 14 upon which the bolster 15 rests. Extending upwardly from each end of the bottom member 10 is an inclined and tapered tie beam 16 terminating in an oil box extension 17.

vided at its lower edge with aT-flange 18 extending to the lower edge of the oil box extension 17 and at its upper edge withl a T-flange 19 extending to the upper edge of the oil box extension 17. Extending upwardly from the junction of the lower vmember 10 and the tie beam 16 is a truck column 20.'- Extending between the-truck. column *f and the tie beam 16 is a flange 21'having 0.3 med mit an opening 22 to allow inspection ofwthe brake hanger and brake shoes. Thisv web 21 has at its upper edge aT-lange 2.3gioining the T-ange 19 on the u'pper edge This tie beam 16 is pro-v l l l l bolts 29 passing down through the oilbox extensions 17 and through short tie bars 30 passing below the` oil boxes 26 and secured by means of bolts31 in` pockets 32 formed inte- 65 gral with the tie beams 16. Formed integral with each of the webs 21, on the inner side thereof, is an angular member 34 for supporting thc brake-hanger. lfiiveted, or otherwise secured, to each of these angular memvbers 34, is a second angularmember 35, to

which in turn is secured an angular member 36, between which and the me ber 35 the brake-hanger 37 is pivoted, as best shown in` Figs. 4 and 5.4

By the use of the short tie beams 30 in place of the usual arch-bar extending below the side frame, I am enabled to keep the side frame at the required distance from the rails and at the same'time secure room 'for a greater amount of eiiectively disposed metal in the side frame, thus greatly .increasing its strength, and at the same time I avoid weak: ening the side frame by bolt holes for securing the arch-bar in position. Moreover, 35 the metal in my side frame is so disposed as y to secure the greatest possible amount oi strength and at the same time. suitable provision is made for the inspection of the brake-hangers and brake shoes. 90

Having fully described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a car truck, the combination with the bottom member and truck columns of a side frame, of tie beams extending upwardly from the base of said truck columns, oil box extensions carried by said tie beams, ro-t jections extending from the edges of sai tie beams and provided with pockets, and tie 100.

of the tie beam 16. Formed in the T-ilanges and provided with pockets open at their upT 23 are depressions 24 adapted to receiveareper sides and outer ends, and tie bars se- 11o cured in said pockets under the oil boxes.

3. In a car truck, the combination With the bottom member and truck 5 side frame, of tie bea-mf;v

1n said the oil said rejections and tie bars.

4. n a car truck, the eombin bottom member frame, of tie beams extendi pockets and adapted to tensions carried by said tie b tions 'carried by the edges of s and provided with pockets ope bars secured extend under boxes, and bolts extending tlirougli ation with the and truck/,columns of a side ng upwardly earns, projeeaid tie beams n at their upperv sides and outer ends, tie bars secured in said pockets and adapted te extend under the oil boxes, and bolts extending vertieally "the bottom member and truck vriside frame, of tie beams inclii from the base of said truck col throrgli said projections and tie bars. op 5. a car truck, the combination with columns ol a ied upwardly umn and provided with oil box extensions, the upper edges of said tie beams having T-langes extending to the upper edges of said oil box extensions, a Web extending between each ltie beam and truck column,

and a brake hanger carried by said web the said web be tion of4 the brake-hanger.

' 35 ing provided with an opening for the inspec- 6. In a ear truck, the combination with the bottom member andtruek columns of a side frame, of tie beams inclined upwardly 40 from the base of said truck columns and provided With oil box extensions7 edges of said tie beams having the upper T-iianges exthe bottom member and ti'ucl and adapted to extend l tending to the upper edges of sind oil box extensions, a web extending between each tie beam and truck column, a brake henger Carried by said web said web being provided with an opening for the inspeelion of the brakeelmngei, and a removable compression member extending ljietiveen said truck eolnmns.

7, In a car truck, the. cinnbinution with the `bottom member and truck columns oi a. side frame, of tie beams extending upwardly from the base ot said truck Columns and provided with oil box extensions, the upper edges of said tie beams having` i T-llange extendingi to the ui'ip'er edge et said oil box extensions, a -web extending between each tie from the base el said. columns, oil boxexi beam and truck column, and a brake-hanger formed integral with eaeh web, the said web being provided with an speetion oi the brake hanger.
